Sericulture is cottage based industry which combines both the features of agriculture and industry. India has tremendous potential for silk development but yet unexploited, however development is not far away. The current study is an attempt to analyse the share between traditional and non-traditional states and between the states on the basis of mulberry silk production and mulberry cultivation. Regression analysis, coefficient of variation, growth rate was used to attain the objectives of the study. It was found that the traditional states hold the maximum share both in mulberry cultivation during 2012-13 was (82.90%) as well as production of raw silk (96.49%). In which Karnataka, Andhra Pradesh and West Bengal contributes maximum production among traditional states, while as Maharashtra, Manipur and Madhya Pradesh are the leading contributing states among the non-traditional states in total raw silk production in India.
2. An economic analysis of mulberry raw silk production in traditional and non-traditional states of India
Bhat and Choure 016
Sericulture, an age old craft in India is practiced in a
vast geographically diversified areas including,
temperate (Kashmir), sub-tropical (Jammu, Himachal
Pradesh, Uttar Pradesh, North- Eastern Region) and
Tropical (West Bengal, Bihar, Orissa, Madhya Pradesh,
Andhra Pradesh, Tamil Nadu and Karnataka. India is
the Second largest producer and largest consumer of
silk in the World and has the distinction of producing all
the five varieties of silk viz. Mulberry silk, Eri silk, Tasar
silk, Oak Tasar and Muga silk. In 2012-13 Mulberry
accounts for 90%, Eri 8.0%, Tasar 1.9%, and Muga
0.7%, of the total raw silk production of 23679 MTs in
the country.
Sericulture is practiced as subsidiary occupation from
ancient times but before few decades it has gained a
momentum in its growth due to the fact that it is no
longer confined to traditional area, now providing
gainful employment even in non-traditional sericulture
areas. However the traditional states still retains the
control over supply of mulberry silk by contribution
96.46% during 2012-13, irrespective of the fact that
non-traditional states constitutes about 20% of land
area under mulberry cultivation. The maximum
contribution comes from Karnataka (43.82%), Andhra
Pradesh (34.92%) then West Bengal (10.68%), Tamil
Nadu (6.32%), J&K (0.76%), while none of the non-
traditional states contributes more than 1%. However
as far as area under cultivation is concerned some of
the non-traditional sericulture states have equal or less
than 3% during 2012-13. The non-traditional states
contribute only less than 4% in total mulberry raw silk
production and mulberry cultivation area constitutes
16.10% during 2012-13 (CSB 2012-13). This clearly
shows the inefficiency of production in raw silk by the
non-traditional states of India. The difference between
traditional and non-traditional states is due to differing
costs of production of mulberry leaves and rearing
silkworm.
Objectives
1. To find out the share of traditional and non-
traditional states of India in the mulberry cultivation and
raw silk production.
2. To analyse the instability and growth in raw silk
production in traditional and non-traditional states of
India.
Hypothesis
Null Hypothesis: There is no significant relationship
between mulberry raw silk production and mulberry
cultivation.
Alternative Hypothesis: There is significant
relationship between mulberry raw silk production and
mulberry cultivation.
MATERIAL AND METHODS
The present study makes use of secondary data from
the relevant publications, Reports, records and internet.
The Study is all about India’s traditional and non-
traditional states. The traditional states are those
states, which are practicing sericulture from ancient
times while as non-traditional have adopted this
practice recent times. The different tools which have
been used in this analysis are T-test, Coefficient of
variation and growth rate. The OLS regression model
was used to find out the relationship between the
mulberry raw silk production and mulberry cultivation.

RESULTS AND DISCUSSION
Mulberry Raw Silk Production in Traditional States
In traditional list only five states are there Karnataka,
Andhra Pradesh, Jammu and Kashmir, Tamil Nadu and
West Bengal. This group of states holds the grip over
the mulberry silk production and mulberry cultivation in
India. The traditional states produce 96.49% of raw silk
from 80.90% of acreage during 2012-13. The total
production of raw silk during 2012-13 was 18096 MTs,
in which Karnataka (Silk Bowl of India) produces 8219
MTs (43.82%) and emerges as the leading Mulberry
Silk producer in India. The other contributing states
according to their share in total mulberry silk are
Andhra Pradesh (34.92%), West Bengal (10.67%),
Tamil Nadu (6.32%) and Jammu and Kashmir (0.76%).
As far as mulberry cultivation is concerned, maximum
area under cultivation comes from Karnataka (40.15%),
Andhra Pradesh (23.19%), West Bengal (7.40%), Tamil
Nadu (8.95%) and Jammu and Kashmir (4.06%)
(Central Silk Board). It is clear from the above analysis
that there is direct relation between area under
mulberry cultivation and mulberry raw silk. From Table
1; it is clear that contribution among the Traditional
states and contribution in all over India is almost equal.
It is due to the fact that non-traditional states
contribution is less than 4% in total mulberry raw silk in
India.

Table 1 also indicates the change of share in
production and mulberry cultivation during 2005-06 to
2012-13. Karnataka is the only state whose share
decreases in both raw silk production and area under
cultivation from 48.37% and 48.99% in 2005-06 to
43.82% and 40.15% respectively during 2012-13. The
reason might be ascribed to the share in services
sector which is rapidly increasing due to modernisation
and urbanisation, those workers who are previously
engaged in sericulture to services sector, due to high
earnings from service and therefore shifting of labours
leads to decreasing raw silk production in the state.
However the other developed states such as Andhra
Pradesh, West Bengal and Tamil Nadu, there is a
meagre increase in production and mulberry cultivation
and in case of J&K, share has been increasing both in
area and raw silk production from 3.14% to 4.84% and
0.61% to 0.76% in J&K respectively.
Mulberry Raw Silk Production in Non-Traditional
States
Those States which are not in the traditional list are
covered under the non-traditional states, such as
Andhra Pradesh, Assam, Bihar, Chhattisgarh, Madhya
Pradesh, Himachal Pradesh, Manipur, Mizoram,
Maharashtra and Uttarkhand etc. They are called non-
traditional because of the fact of cultivating sericulture
from recent times. The contribution of non-traditional
states in total mulberry raw silk production in India is
3.51% during 2012-13 and the share in total mulberry
cultivation is about 17%. Maharashtra (0.90%) and then
Madhya Pradesh (0.60%) Manipur (0.61%), Mizoram
(0.15%) are the leading contributing states to total raw
silk production in India (Table 2). As far as contribution
among non-traditional states is concerned, the above
story repeats as Maharashtra (25.79%) and then
Madhya Pradesh (14.71%) Manipur (17.45%), Mizoram
(4.55%) are the leading producers and rest contribution
states is shown in Table 2. The area wise share of
different states is also analysed and result is shown in
Table 2, and the story is totally different as that of
traditional states because maximum area under
mulberry cultivation comes from Assam, whose
contribution in raw silk production is very low (0.09%),
while as Maharashtra contributes maximum but area
under cultivation is 5.79%. (Central Silk Board) the
interpretation of the Table 2 states that area under
mulberry cultivation does not have any impact on Raw
silk production in non-traditional states of India.
The percentage share in mulberry cultivation and raw
silk production in non-traditional states is shown in
Table 2, it can be inferred from the table that
percentage share is remaining almost constant during
2005-06 and 2012-13, both in mulberry cultivation and
raw silk production in different states of non-traditional
zone. However some of the states showed increments
in mulberry cultivation are Assam, Meghalaya, Manipur
and Maharashtra etc, while other states have shown
increasing trend but with slow pace. Kerala and
Himachal Pradesh are those non-traditional states
which have shown decreasing trend in mulberry
cultivation.
Growth and Instability in Mulberry Raw Silk and
Mulberry Cultivation in Traditional and Non-
Traditional States
The growth and coefficient of variation in mulberry raw
silk production and mulberry cultivation in both
traditional and non-traditional states were analysed and
results are shown in Table 3 and figure 1.1. The
mulberry raw silk has increased significantly at the rate
of 21.43%, while as area under mulberry cultivation in
India has grown marginally at the rate of 3.92 % per
year, therefore it is clear that productivity has shown
increasing trend (table,1.3). In spite of decreasing
mulberry acreage in Karnataka (-14.82%) and West
Bengal (-13.04%) during the period from 2005-06 to
2012-13, but still the raw silk production has increased
at the rate of 10.01% and 28.97% respectively during
the same period. Tamil Nadu, Andhra Pradesh and
Jammu and Kashmir have increasing production of raw
silk as well as area under mulberry cultivation. Tamil

Nadu has achieved 60% growth rate in raw silk
production which is almost double than growth in
mulberry cultivation. As far as non-traditional states is
concerned highest growth rate was achieved by
Madhya Pradesh both in acreage as well as mulberry
raw silk production during 2005-06 to 2012-13. The
growth rate in mulberry raw silk production in different
non-traditional states list has shown increasing trend
except few such as Kerala and Punjab. The Table 3
also shows that area under mulberry in non-traditional
states has grown rapidly due to the growing demand of
silk items and its allied production. With the result that
some of the states like Bihar, Madhya Pradesh,
Maharashtra, and Meghalaya and utter Pradesh whose
area under cultivation has grown more than 200% per
annum.

The instability in mulberry cultivation and mulberry raw
silk production both in traditional and non-traditional
states were analysed. It was found that overall mulberry
cultivation was remained stable during 2005-06 to
2012-13. Non-traditional states are more stable in
mulberry cultivation than traditional states. The
coefficient of variation in mulberry cultivation overall in
traditional states are 70.08% which is much higher than
overall coefficient of variation (13.97%) in non-
traditional states. Whereas mulberry raw silk production
in traditional states in India has shown stability than
non-traditional states and this stability was mainly due
to low coefficient of variation in different states like
Karnataka (2.91%), West Bengal (5.5%), Andhra
Pradesh (8.10), and Jammu and Kashmir (8.10%). The
non-traditional states are unstable than traditional
states in terms of mulberry raw silk production. The
coefficient of variation (CV) of mulberry raw silk
production (35.71%) in non-traditional states is higher
than national CV (7.14%) figure as shown in Table 3.
Table 4 shows that OLS regression model was applied
on different state’s time series data of mulberry
cultivation area and mulberry raw silk production of
different years from 2005-06 to 2012-13. However the
results are different, some of the states showed direct
relationship between these two variables while as some
have shown inverse or insignificant results. The * (star)
figures of the above table shows significant results, so
that it can be concluded that mulberry cultivation has
direct impact on mulberry raw silk production and
results are significant at 5% level of significance. Those
states which are significant at 5% level of significance
shows higher R2
values such as Andhra Pradesh has
